Recently, the human homologous C3 recombinant collagen independently developed by the synthetic biotechnology skincare brand STEE HILL was the first to achieve a human skin permeability test.
CHAILEEDO learned that collagen is vital to human health and beauty, but as a large molecule, its permeability is a technical problem that has not been overcome, and it has never been demonstrated to really achieve permeability in human in-vivo skin. This time, STEE HILL adopted photoacoustic technology for the human in-vivo permeability experiment, and the technology and experiment were jointly completed by Chinese scientists Liu Chengbo's team and Zhang Guangxian's team. This technology presents the whole process of collagen being effectively absorbed by the skin, pioneering the first skin penetration technology in the beauty industry, and also solving the industry problem of "difficult absorption of collagen".
It is worth mentioning that the world's first recombinant collagen human in-vivo skin permeability experiments abandoned the traditional pig and cow skin animal experiments. Instead, the human homologous recombinant collagen C3 solution was applied to the subject's skin, and the whole process of dermal penetration was visualized through photoacoustic/fluorescent confocal microscopic imaging technology. It is reported that this recombinant collagen of STEE HILL C3, which can penetrate the living dermis of the human body, has been registered in the information database of Chinese cosmetic ingredients and declared for Chinese and foreign patents.
Li Jia, the founder of STEE HILL brand, said that STEE HILL brand was founded with the goal of getting rid of the dilemma that the raw materials of China's beauty industry rely heavily on overseas imports. Nowadays, in the development and application of C3 collagen, Chinese synthetic biology begins to lead the world. For the rise of China's beauty industry, independently developed advanced technology and core raw materials are indispensable.
It is known that STEE HILL is a mid-to-high-end skincare brand of Meishen Biologicals, and it is also the only new brand in China's beauty industry that is positioned in synthetic biotechnology skincare. Its main product is the "3C baby collagen" series. The brand has already developed a number of products such as creams, serums, lotions, cleansers, and medical dressings based on C3 recombinant collagen.
In the second half of 2021, STEE HILL's Tmall flagship store will be opened and a full line of recombinant collagen skin care products will be launched. According to the brand, it officially operated in Q4 of 2021, with a growth rate of over 200% compared to Q3, achieving a gross profit of 87% and a repurchase rate of over 25% of sales data. In August this year, STEE HILL completed tens of millions of RMB angel round financing.
Furthermore, STEE HILL has also cooperated with two prominent bio-industry leaders, such as Bluepha and Shandong Focusfreda Biotech, as well as dozens of opinion leaders in the beauty and skincare field, such as Yanantang and Tsinghua skincare senior Wang Zhi, to jointly launch the "Exploitation of the Works of Nature" clean beauty biological raw material library, and jointly initiative for new synthetic biological alternatives to chemical synthetics, zero microplastics in raw materials and production processes, simple and degradable packaging materials, and more alternative technologies to animal testing.
